Hold down Command -R at startup. This invokes recovery Mode and gives access to Utilities.
Run Disk Utility.
Select your drive by Hardware_name.
Check SMART status in lower right.

The following support article is somewhat outdated. Where it refers to booting from an installation disc, you should boot from your recovery partition (if running 10.7 or later) by holding down the key combination command-R at the chime. If your startup volume is encrypted with FileVault, you’ll have to unlock it in Disk Utility before you can do anything with it.

Got grey screen to Disc utility by pressing Command R but option to repair greyed out. Cannot access disc utility despite highlighting drive in left column. Back to grey spinning wheel. Any further ideas?
